SHOCK-ABSORBER.

Application ined July 6, 1914i` To all .1r/"icm .fr iii/zy Concern:

Be it known that I. AUGUST MAGIX. a citizen of the l 'nited States, residing,y at RochesA ter, in the, county of Monroe and State of New York. have imented certain new and useful Improvements in Shoekwkbsorbers, ot which the following is a specification.

The object of this invention is to provide a n' w and improved shock absorber.

i and other -zv'njects of the invention l ne fully illustrated in the drawings. deribed in the specification and pointed ont ir. :he claims at tir" end thereof.

la ille drm-vin; 1*"igiii'e l is a side elevation oi the shock absorber as it will appear `in place on the car when viewed from the ot' the ci3 is a verticalsection i line Fig. 1. lig is a line 3*-3 of Fig. ig upward. i is a horizontal section on the line. Qt" Fig. 1, looking downward. Fig. 5 is a detail perspective View of one of the supporting brackets used in my absorber.

In the drawings like reference numerals indicate like parts.

In my shock absorber are provided the cylinders 1 and 2. The cylinder 1 has cast thereon thel reduced neck 3 and the lugs 4 and 5. The cflinder 2 lhas casi, thereon the neck 6 and the lugs 7 and 8, Mounted 0n each of these cylinders are the brackets Y) and 10 respectiwxly. rl'hese brackets are duplicates of each other., one of these brackets being shown in perspective in Fig. 5. As shown in Fig. fi at the rear end ot' the bracket il is provided the ears 11 and 12 which embrace opposite sides of the cyiinder 1. The bracket is recessed at 13 to receive the Harige ll on the top of the cylinder. On the bracket i) is also provided the boss 15 which perforated at 16 to receive the stud or pin 26. The bracket is also formed with :i guide 17 which engages with the side of 3 which is made square on one .side

a bearing there for. the other side i being left hall' round.

The neck: J3 and (l are perforated to receive the stems 1S and 19. These stems ex-l tend down into the cylinder and have on the lower ends thereof. the piston '.0 which is held thereon by the nut 21. Between the piston 2() and the top of the cylinder is pr0- vided two compression springs 22 and 23. The bottoms of the cylinders are closed with the caps 24 and 25 respectively. At the top,

the stems 18 and 19 are proyided with the. hearings :39 and 30 which ar 'fastened thereto in any suitable manner, being preferably threaded and crazed into them. Each of these bearings is provided witha recess shown in dotted lines at the top of Fig. l and by full lines in Fig. 2. In these bearings is supported the stud 31.

After the cylinders, sprin s and piston are assembled, in the manner eretofore described, the two cylinders are connected together as follows:-The brackets 9 and 10 are placed on their respective cylinders and the cylinders, brackets and bearings are brought. together with the bolts 27 and 28 and the pins or studs 26 and 31 placed in their respective places. The brackets and bearings on the pistons are held apart by the pins 26 and 31 and the brackets and cylinders are held apart and fastened together by the bolts 27 and 28.

The bolts 27 and 28 are suitably shouldered for the purpose 'of holding the cylinders andI brackets apart and are provided with reduced ends which pass through the openings providlld inthe brackets and the lugs on the cylinders. These reduced ends are threaded to receive the nuts by which the cylinders and brackets are suitably clamped together. holding the stud 2li in place. the stud 2G being! lonpr enough .to span the opening between the two brackets 9 and 1U and till the openingr in the two bosses 15, so that it extends between the lint inner surfaces of the necks 3 and (i by which the stud il) is held against longitudinal movement. The stud 3l is long enough to ,span the opening between the bearings 2.() and 30 and lill the openings in said bearings by which bearings it is held against longitudinal movement.

In use, thisl shock absorber is interposed between the body and axle of an automobile in the ordinary manner, the stud 31 being connected directly or indirectly to the axle and the stud 2U being connected directly or indirectly to the body of the car, the ordinary method of fasteningr being to the springs that are connected to these two parts, of the car. Yhen the axle raises or the body falls in the running of the car. the studs move accordingly andthe springs- 22 and 23 are compressed, causingr the movement to be taken up locally so as not to be communicated to the large springs or the car body.

ln applying shock absorbers to dilcrent types ol" cars it is necessary to vary the tance between centers of the pins il() and 3l. This is done by turning` tle nut Zl cn the stems or piston reds 18 and 19 nhicii raises or lowers thc pistons or by substituting brackets of dill'rrent lengths for the brackets 9 and .'10 so to carry the pin 26 higher nr lower as may be desired or by doing both oi' these things. A considerable wear tales place between the pin 2li and its beam. 1: and when the parte become uns-em because of weer, the brackets S and pin i215 can be replaced by nevv part-:s thus bermitting the use el old cylinders. The pin 31 wears less rapidly than the inn due to the difference in the thrust that it receives and due to the fact that it supported in longer bearings.

I claim:

1. In a shock absorber the combination of a pair of cylinders, springs carried in said cylinders, a piston and piston rod carried in cach cylinder, said piston working tc coinpress said springs, the pistcn rods extendingl out of said cylinders and being conncctcd for joint operation by a. beni-intr pin. said cylinders being also connected for joint operation, said cylinder connections including a bracket clamped to each of said cylinders, each of said brackets having an ear in each side thereof, pins t0 clamp said ears to said cylinders and hold said brackets a predetevnined distance apart, a pin supported between said brackets.

2. In a shock absorber the combination cf a pair of cylinders, a. pair of lugs on the sides of each cylinder and a flange and a neck on the to of each cylinder, a bracket clamped to eac cylinder, each brackethaving a pair of lugs adapted to bear against the lugs on the cylinder, a laterally extending recess adapted to receive the flange, a vertically extending recess adapted to receive the neck of the cylinder,

3. In a shock absorber the combination of a pair of cylinders, pair of lugs on the sides of each cylinder' and a flange and a neck on the top oti each cylinder, a. bracket clamped to cach` cylinder, each bracket having a pair of lugs adapted to bear against the lugs on the cylinder, a laterally extending recess adapted to receive the flange, a 'vertically extending recess adapted to receive the neck of the cylinder, a. pair of bolts having shouldered ends for clamping,r said cylinders and brackets together and for holding said cylinders suitably spaced apart.

fr. ln a slicck absorber the combination of a pair of cylinders, a pair of lugs on the sides of each cylinder and a Harige and a en the top of each cylinder, a bracket clamped to cach cylinder, each bracket having a pair of lugs adapted to bear against the lugs on the cylii'lder.y a laterally extending recess adapted to receive the lange, a 'vertically extending recess adapted to receive the neck or" the cylinder, a pair of bolts having shouldered ends for clamping said cylinders and brackets together and for holding said cylinders suitably spaced apart, a pin supported between saidbrackets.

5. ln a shock absorber the combination of a pair of cylinders, springs carried in said cylinders, a piston rod carried in each ol said cylinders, hearing plates on each side of .said cylinders. means for rigidly connecting and spacing apart said learing plates, said piston rods having a bearing pin mounted locscly between them at their ends and mov-- ing therewith, said cylinders also having a bering pin loosely mounted between them anti moving therevv'ith.

In testimony whereof I affix my signature in presence of two witnesses.

AUGUST MAGIN.
